What does Israel have in its arsenal that it could use against Iran?

Israel has airborne and naval capabilities that it can use against Iran, but it must choose any target carefully.

On Friday morning, Iranian air defences shot down three drones above its central province of Isfahan.

Iran has yet to announce the results of its investigation into the incident, but the US said early on that Israel launched the attack. Israel has not commented despite speculation that it was behind it.

Observers have, however, been anticipating an Israeli attack on Iran as the next link in a chain of escalation that began with an April 1 attack on the Iranian mission in Damascus that Iran blamed on Israel.

The second was Iran launching 331 drones and missiles towards Israel on Saturday night in a well-choreographed attack, giving rise to expectations of an Israeli response.

But if Israel were to strike Iran, how would it go about it?
